To all whom/it may concern: Be it knownthat L'EDMUND K. BAKER, a` citizen of the United States, residing at Springheld, in the county of Hampden and State of Massachusetts, have invented new and usemechanisms, allfsubstantially as will hereinafter fully appear and be set forth' in thel claims. r The invention panying drawings, in whichy Figure 1 isafront elevation of theimproved spinning machine.

Similar'characters of reference indicate corresponding parts in vall of the views.

The machine will be described with reference tothe particularconstructions and formations here shown, while at thesame time it is understood that as certain -parts ot the invention are contemplatedin their broader aspect the invention is not tobe limited to thedetail construction of the particular instrumentalities shown. l

In thedrawings, A represents the framing of the machine which occupies a rectangular space', and has at its middle part the horizontal driving shaft, B, with the driving pulley, B2. This shaft, B, also carries the drum, C, which through the usual banding, c, c, drivesl the spindles, Z, Z.

' The framing, A, has, toward each end, theuprights, A2, A2, having between them the spool, or beam, D, for the roving, x. This spool has end studs, 20, which loosely play inthe slotted guide-Ways, 22, of the standards,

A2, while the cylindrical body constituted by the wound rovings on the kspool rests, for frictional contact, at its under side upon the upper 'side of a cylinder, E, mounted on the shaft, E2, which has fixed on one extremity the lratchet wheel,'23. On one extremity of said cylinder shaft, E2,.is,afloose sleeve, a, having thereon a spur gear wheel, 24, a disk, 25, with'a cam-rib, 26, on its face and a radial arm, 2 7, which has a pawl, 2S, lpivoted near its extremity, said pawl also having the offset finger, 29. Y The spring, 30, exerts the pressure to place. the -pawl in engagement with thev ratchet wheel, 23. The gear-wheel, 24, is in mesh with a spur pinion, 16, supported on the stud, 17, having thereon the' v o utside of, the edge'of the ratchet wheel, 23,

is an arc-shaped guard, 32, having an extent roo lcorresponding to a portion of the circumference of the ratchet wheelQ,A As the sleeve, a,

continuously rotates and the arm,27, revolves,

the pawl, 28, part of the time is in engagement with the ratchet wheel, causing then a rotational movement thereof and of the drum, E, which insures the delivery of the roving, while at other portions of the period of` each rotation of the sleeve, the finger, 29, by being engaged by the said guard, 32, results in the cessation of the movement of the ratchet and delivery drum.

The rovings run off from the spool, or beam, D, through simple feed-rolls, 61,6?, which have intermittent motions concurrent and uniform with those of the drum, E, tothe drawing and twisting heads. Said motions of the feedrolls are imparted from the drum shaft, E2,

l by parts in arrangement as follows: The feed rolls, d, of the lower series are mounted on the common long shaft, d3, having bearings in the said uprights, A2, A2, and this shaft at one end is provided with the sprocket Wheel d4. There is another sprocket wheel, e, which is mounted on one nd upright, A2, and which turns as one with t e pinion, c2, formed thereon, or attached thereto, which meshes with .the gear-Wheel, e3, on the end of shaft, E2.

Themdrive chain, e4, passes around sprocket wheels, e2 and d, As shown to accord with the set of drawing and twisting mechanism which is arranged at the rear of the machine, as Well as the front, this drive chain is also passed around the duplicate sprocket wheel, d, geared to the lower common shaft for the second set of feed rollers. The upper feed rolls, d2, are mounted for individual and independent swinging movements to have pressure bearings by gravity on the lower rolls, cl, upon which latter rolls the said upper rolls,d2, are supported. Each upper feed roll is, therefore, mounted in a yoke, or swing frame, the

rear or inner end of which is hung on `the long rod, d5.

The individual combined drawing and twistingV heads, G, G, are shown as mounted in long, hollow rails, or boxes, 50,at the front and rear of the frame, the axes of the rotary bodies,f, being oblique, they extending rearwardly and upwardly, while the axes of the paired parallel drawing rolls, g, g, are at right angles to the axis of the head. The twisting bodies have continuous and uniform rotary motions, while the feed rolls have continuous, but variable, rotary motions, at a different speed from the twisting bodies; and the detail construction of one of these heads will be now described in detail:

The combined twisting and drawing head comprises as to the body,f, a construction, intermediately, in the. form of a cubic box with opposite side walls, 52, -52, the sides at right angles to these being recessed, or open,

while the extremities of the head are consti-` tuted bythe exteriorly cylindrical journal members, 53, 53,'which are fitted for free ro- `tary movements in the circular holes, 54, in `the upper andlower obliquely tipped boards of the hollow rail, 50. 'These end portions of the body have the hollow, outwardly opening,

spaces, 55, also communicating with the intermediate chamber, or opening, 56. The body has the fixed, or integral grooved rim, or pulley, h, toward one end, while at its other end portion it receives, loosely, the sleevelike part which exteriorly is formed to constitute the grooved pulley, t', and inside thereof the bevel gear j the teeth of which, instead of being radial to the center of the axis of the gear, are tangential to a smaller circle within the perimeter thereof (see Figs. 6 and 4) whereby the said gear, j, may mesh with the bevel pinion, g2, on the end of one of the pair of drawing-rolls, g, g. These drawing rolls are journaled in the space within the middle of the said body, their axes being parallel with each other, and at right angles to the axis of rotation ofthe head as a whole. The shaft of the drawing roll which has the bevel pinion, g2, thereon also has, at its opposite end, the spur pinion, 57, which meshes into the like pinion, 58, on the shaft of the other drawing-roll, g. The journal bearings of this latter drawing-roll are spring-pressed and yielding and are mounted in the side walls of the body, as follows: The side walls, 52, have the rectangular recesses, 59, 59,- extended from their edges in the base of each of which is the screw-tapped socket for the screw, 60, the head of which stands outwardly beyond the base surface; the journal-box, or support, 62, with the edgewise journal opening, 63, is set in one of the recesses, 59, its loweredge resting on the protruding headof the screw, 60. Thejournal box, 63, has on its outer side the edgewise eX- tended flanges, 64, which overlie the outer Wall of the twister body and one of these flanges is slotted, as seen at 65, parallel with the length of the recess, 59and with the movement of the journal support; and the headed screw, 6 6, holds the box against displacement, laterally of its front face. The springs, 67, 67, press the movably journaled drawingroll IOO against its fellow whose rotation is, as already t seen, about a fixed axis. The spring arms for the two journals may be formed in a single piece, the right angular' bar, 68, being formed integrally with the spring arms. The rib, 69, forms a rocking bearing for this double spring and the regulating screws, 70, 70,

determine the yielding pressure which the drawing-rolls are to have, the one toward the other, for the most efficient drawing effect upon the roving. The drawing-rolls may be of any of the Well known or approved forms, as for simple drawing. out with respect to this peculiarly constructed twisting and drawing head that should the driving of the pulley, z', be at exactly the same rate as the driving of the pulley, h, the bodily rotation for twisting of the twisting Vbody would be unaccompanied by` any rotary motion ofthe drawing-rolls, but that anyvariation in the speed of rotation of relative to that of the twister-pulley, h, will cause the driving of the drawing-rolls through 'the gearing, j, g, and 57, 58. The pulleys, h,

It will be here pointed the pulley, t', l

i of the twister heads are'driven bythe bands,

h2, from the drum, H, whichV has a constant rotary speeding, while thev drawingroll` vpulleys, i, are driven by the bands, which are rotated at a variable speed from the drum, I.y

Asshown in Fgs. kl and 2uthedru`m,lH, is

f driven fromthe spindle drum, C, through the AIo ' stud, n2.

i arbor of the drum, H. An endlesszband, 80,

sprocket wheels, 74, 75, and drive-chain, 76.`

The drum, I, has on its arbor a gear, m, which is larger der, o, which rotates in peripheralv proximity, but not in contact, with the cone, p, on the passes loosely around the cone, having a continuous running motion in unison with they of `the cone, and f, by vbeing borne upon peripherally by the cylinder, the. cylinder has a surface speed corresponding surface speed to] that lof the cone. These driving parts are so formed anddesigned that the twister pul;

' ley, h, is rotated fasterthan the pulley, i, for

twist may be, for instance, three the drawing-rolls,l all whereby the amount of or four to every inch of the drawing of the-roving. At the time of the left-offv of roving the drawing roll pulley, i, has a retarded motion.(so that of the attenuated condition of the roving) at which time the drawing action relative to the amount of twist imparted. to the rovingis the slowest. This actionisassured by reason of the impingement of the cam, 26, upon the roller stud, 7a3, of the lever',c, practically at the beginning of the period of let-0E, so thatthrough the swinging of said lever, lo, the band, 80, is moved along the cone toward its smaller end whereby the rotational move' ment of the drawing-rollpulley, t', is, slowed, producing thereby a" greater difference between its spoed and the speed of the twisterbody pulley, h,the degreevof which .differ-v ence determines the increased'rate of speed of the drawing-rolls. This shifting of the band, for the purpose stated, is insured lthrough the medium of the'band-shifting-lever, k, whichis intermediately pivoted at k2, one end havingr an'engagementl with the band, while its other carries afriction roll, through which it receives the actuating impingement of the aforementioned cam-rib, 26,- ofthe disk, 25, which is on thesleeve, a, before described as entering into the composition of -the inter-y mittent let-olf mechanism vfor the roving. i

The spindles, Z,- Z,-one for each [of the twistingand'd rawing heads, G,are mounted, i

as usual, on the horizontal rail at each side than the' engaging gear, fn, on the Onl said stud, n2, is also the cylin-v Alies between ofthe machine, they bein very rapidly'driven by the driving-bands, c, c, which run around, i

their respective whirls and the drum'on the main shaft in the usual manner. The rovings drawn under twist bythe heads emerge from the' heads devoid of twist, and ruuthrough theguides of the usual rising andfalling rail, J, Fig. 1, to .the rapidly driven bobbins carried'lby the spindles, which impart thevfmal, or yarn-twist. A v.

, The cam-rib, 2,6, is abrupt at l its forward end'andis gradual .in vits hind end inclination," whereby, when fthe roving spool is given its let-off, the acceleration of vthe drawing is immediately at its maximum, and so that after the roving has beengiven its entire let-0E,

the slowing of the-drawing speed becomes gradual to its regularminimum speed. In practice, new roving'is let olf ateachrotation of the sleeve, a, in an extent to reach about half-way from the bite of the feed-rolls, d, dito the heads, G; and that roving which the forward end ofthe newly drawn'off portion and thefhead, G, has, at suchtime received nearly, if'not quite, its ultim'ate'amountof elongation.

AIn Fig. 9 the shaft on whichis the,drum,H, for, driving the tw'ister-body-bands, h2, indi cated as the driving shaft, it having the drivin g-pulley, H2 shaft as before. The cylinder, o, instead of being mounted'on astud and geared to the arbor of drum,l, which-drives the drawing-rollbands, t?, has its stud, or arbor, hung by a and the cone pis shown on thisl IOO universal joint at 03, to thearbor of drum, I, for

the attainment of the resultderived by the exercise of the other described mode of variably driving the drum, I. Again,in` Figs. '10, 1l, and 12, instead of having the arbor of the spindle driving drum to constitute the driving shaft, as in the firstv described arrange'- ment, I have the drum, H, which runs the bands, h2, for driving the twister-body, the driving shaft. This shaft through its cone,

o2, imparts, as the band is shifted substantially as described, the variable speed to the drum, I, which runs the bands which drive the drawing-rolls. The spindle-drum, C, has the' gearing, t, tand t?, whereby it receives its proper running speed. from the drivingdrum, H, and thisv gearing may be readily interchanged, or substituted, by other gearing IIO `lo, and the endless band, 80, and second cone,

scribed arrangement is therefore desirable,

but where it may be assured that the machine will be kept atwork on a certainv character or rovingand for the production of a given kind of yarn,the arrangement of the drivingA seen in Figs. 1 and 2,--Wherein the .spindle drum is on the driving shaft,--may be pre-f ferred. Y f
